Component of the tectonic-like complex, a complex localized at the transition zone of primary cilia and acting as a barrier that prevents diffusion of transmembrane proteins between the cilia and plasma membranes. Required for hedgehog signaling transduction (By similarity).

This gene encodes a type I membrane protein that belongs to the tectonic family. Studies in mice suggest that this protein may be involved in hedgehog signaling, and essential for ciliogenesis. Mutations in this gene are associated with Meckel syndrome type 8. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Oct 2011]

Gene RIF (2)

Network building strategy led to the proposal of candidates for new ciliopathy disease genes, leading to the identification of the first human mutations in the Nephronophthisis gene Ataxin10 (ATXN10) and Joubert syndrome gene Tectonic2 (TCTN2).
